I have these dots on the inner sides of both feet as well as right behind my toes. I have had these for over 10 years, They do not hurt. I have noticed that they are starting to appear on the backs of my calves.
I was doing a lot of leg work at my job about 8 years ago and my doctor just said they were broken vessels... so i left it at that. Now that they are appearing on my calves and i have a desk job i question it.
